BASKET LINER Filed Oct. 8, 1929 2 Sheets-Sheet 2 Patented Mar. 1, 1932 PATENT OFFICE JAMES W. TREW, F BALTIMORE, MARYLAND BASKET LINER Application filed October 8, 1929. Serial No. 398,237.

This invention relates to a basket liner and has relation more particularly to a liner of this kind especially designed and adapted for use in connection with a well known method of packing embodying the use of a tub in which the liner is initially positioned for filling and after which, upon removal of the tub, a basket is applied over the filled liner.

It is an object of the invention to provide a 0 liner of this kind constituting what may be termed an endless wall and which is provided with means to assure the breaking of the liner at a predetermined location as a result of abnormal pressure from within, the remaining 5 portion of the liner being of sufiicient strength to resist such strain.

Another object of the invention is to provide a liner of this kind constituting an endless wall and produced from paper stock,

said stock'at a predetermined point or points thereon being weakened as by slits or openings to permit breakage of the liner at such localities or places as a result of abnormal pressure from within the liner, the webs between said openings or slits initially therebetween possessing sufficient strength to maintain the filled liner in column independently of any external support.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved basket liner whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will behereinafter more fully set forth. v

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in perspective of. a liner constructed in accordance with an embodiment of my invention; t

Figure 2 is a vertical sectional view showing my improved liner applied within a tub or shell arranged upon a conventionaltype of facing form;

Figure 3 is a view partly in section and partly in elevation illustrating a filled basket with my improved liner therein partially broken;

Figure 4 is a view in perspective illustrating a liner constructed in accordance with a further embodiment of my invention;

Figure 5 is a detailed sectional view taken substantially on the line 5-5 of Figure l;

Figure 6 is an elevational view of the con necting tape unapplied.

In the embodimentof the invention as comprised in Figures 1 to 3 inclusive, my improved liner L is produced from a blank of requisite dimensions, the extremities of which being pasted or otherwise substantially permanently connected so that the completed liner constitutes an endless wall. The liner L is made from paper stock or the like of suflicient inherent strength not to break or yield under the influence of the load therein.

In this embodiment of my invention, the liner is weakened at substantially diametrically opposed points and in a plane radially of the liner substantially at right angles to the radial plane in which is positioned the connected overlapping portions 1 of the liner. Each of these weakened portions, as herein disclosed, is afforded by providing a series of elongated narrow slots or openings 2 arranged in a line extending from the top to the bottom of the liner with the spaces or webs 3 between adjacent openings or slots 2 being each of a width equal to the length of a slot or opening 2.

It is preferred that the slots or openings 2 be ofthe same length. It is also to be noted that the end openings or slots 2 are positioned inwardly of the end edges of the liner L so that the opposite free end marginal portions of said liner are unbroken.

In the use of this improved liner the same is snugly engaged within a tub or shell T and said assembled shell or tub and liner L are then properly positioned upon a facing form F upon which has previously been arranged a layer of fruit. The liner L while in the shell or tub T is then filled with fruit whereupon the shell or tub T is removed. The liner L is of sufficient strength to maintain therealong with a series 0 the liner and its content in column so that an inverted basket B may be disposed thereover in a well known manner. The basket B with its load is then upended as illustrated in Figure 3.

Should the liner L with its load when received within the basket B be of sufiicient lateral or radial dimensions as not to snugly fit within the basket B, abnormal pressure imposed outwardly ket occur at the lower portions thereof. Of course, if demanded, the liner will break from end to end. This breaking of the liner L within the basket B results in the load having a firm pack within the basket thus assuring a full content. It has also been fully demonstrated in practice that with the 'liner having a plurality of predetermined weakened portions the breakage will occur at one of such portions. It is, therefore, to be understood that if desired the, liner L may be provided with only a single weakened portion.

In the embodiment of my invention as illustrated in Figures 4 to 6 inclusive of the drawing's, the liner L is formed from a suitably designed blank of paper stock, or the like with the free ends thereof brought into relatively close proximity one to the other but not in overlapping'relation. An elongated tape A of desired paper stock is employed to hold said adjacent ends in desired relation resulting in the production of a liner of an endless wall type. As is particularly illustrated in Figure 6, a faoe of the strip or tape A has disposed thereover an adhesive coating 4 whereby the strip or tape may be readily and-conveniently applied in desired working position. This stripvor ta A is provided 7 spaced openings or slots 5 arranged in alignment, and when the strip or tape A is applied, 'said'openings or slots 5 are positioned between the free ends of the blank of the liner L proper and for 'which reason said free ends, as illustrated in Figure 4, are separated a distance suflicient to allow for such positioning of'the openings or slots 5.

The applied liner as comprised in this sec- 0nd form of my invention is intended for use in the same manner as hereinbe'fore set forth with respect to the first embodiment of my invention and the strip or tape A possesses suflicient strength to assure the liner and its con tent being maintained in column free of any qualities between the filled liner and the basindependent support. However, upon abnormal pressure from within the strip or tape A will break. This is of advantage after the liner and its content is arranged within an upended basket as it assures a firm and compact package just the same as hereinbefore set forth with respect to the liner L.

-It is also to be understood that the blank from which the liner L is made constitutes paper stock of a strength which will not yield or break as a result of the strain imposed upon the liner from within during a packing operation, or as a result of the handling. of the completed package. In other words, the applied strip or tape A provides means to permit breakage of the endless liner at a pre determined location upon the liner.

From the foregoing description It is thought to be obvious that a basket liner constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may beassembled and employed, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereofiand for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown: in carrying out my invention in practice except as hereinafter claimed.

I claim 1. As a new article of manufacture, a hasket liner for use in packing fruit consisting of an endless wall of a strength to hold a col- 7 1 umn of fruit without any independent support, said wall at a. predetermined point being weakened to render it susceptible of breakage under abnormal pressure om within, said weakened portion extending from substantially one end to the other of the liner, said weakened portion terminating inwardly from the ends of the liner.

2. As a new article of manufacture, a basket liner for use in packing fruit consisting of an endless wall of a strength to hold a column of fruit without any independent support, said wall at a predetermined point being weakened to render it susceptible of brea age under abnormal pressure from within, said weakened portion constituting a series of spaced openings in the wall extending substantially from one end of the liner to the other, the end openings being spaced inwardly from the ends of the liner so that the marginal portions of the liner are unbroken.

In testimony whereof I hereunto afiix my signature.

JAMES W. TREW.
